The Daylite Xenon Light Source is indicated for use in surgery and medical applications where high intensity illumination is required
The Daylite XeNon Light Sources are comprised of high intensity xenon light sources, fiberoptic cables and fiberoptic headsets. The Designs for Vision Daylite Light Sources are supplied with headsets that were first placed into service prior to 1976 and are preamendment devices. The Designs for Vision headsets have been marketed since the early 1970's with a long history of safe use in the surgical suite. The headsets are either coaxial, bifurcated, or focusable designs. The light source includes a universal chuck for fiberoptic cable attachment. The universal chuck accepts various sizes of light cables. The XeNon Light sources provide either 180-watt or 300-watt power output and contain a continuous illumination level adjustment which provides 6000°K color temperature light.
The provided document K013880 is a 510(k) summary for the Designs for Vision, Inc. Daylite XeNon Light Sources. This document is a premarket notification for a medical device and describes its substantial equivalence to predicate devices, focusing on regulatory compliance rather than extensive clinical performance studies.
Therefore, many of the requested details about acceptance criteria, detailed study design, and ground truth establishment are not typically found in such a regulatory submission. A 510(k) primarily demonstrates that the new device is as safe and effective as a legally marketed predicate device.
Based on the provided text, here is the information that can be extracted or inferred:
1. Table of Acceptance Criteria and Reported Device Performance
The document does not provide a table of explicit acceptance criteria or detailed performance metrics. Instead, it relies on demonstrating electrical safety characteristics and substantial equivalence to predicate devices.
| Acceptance Criteria (Inferred from 510(k) requirements) | Reported Device Performance |
|---|---|
| Electrical Safety (Implicit requirement for medical devices) | "Testing has been performed which demonstrates the electrical safety characteristics of the Designs for Vision, Inc. Daylite XeNon Light Sources." |
| Same Intended Use as predicate devices | "The Daylite Xenon Light Source devices have the same intended use as the predicate device..." (Indicated for use in surgery and medical applications where high intensity illumination is required.) |
| Similar Technological Characteristics to predicate devices | "...and similar technological characteristics. They all consist of Xenon Light Sources supplying fiberoptic illuminators with illumination for headlights." |
| Preamendment Status of Headsets (Implicit acceptance of existing technology) | "The Designs for Vision headsets were first placed into service prior to 1976 and are preamendment devices... a long history of safe use in the surgical suite." |
| Power Output: 180-watt or 300-watt (Characteristic, not a performance target against a criterion) | Provides either 180-watt or 300-watt power output. |
| Illumination Level Adjustment: Continuous (Characteristic) | Contains a continuous illumination level adjustment. |
| Color Temperature: 6000°K (Characteristic) | Provides 6000°K color temperature light. |
| Universal Chuck for Cable Attachment: Accepts various sizes (Characteristic) | Includes a universal chuck for fiberoptic cable attachment, accepting various sizes of light cables. |
2. Sample Size Used for the Test Set and Data Provenance
The document states "Testing has been performed which demonstrates the electrical safety characteristics." However, it does not specify a sample size or data provenance (e.g., country of origin, retrospective/prospective) for any test set. This type of detail is usually found in detailed test reports, not the 510(k) summary itself. The testing mentioned would likely involve a limited number of manufactured units to verify electrical safety standards rather than a clinical trial with patient data.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications
Not applicable. This device is a light source, not a diagnostic or AI-driven decision support system that requires expert-established ground truth from clinical cases. The "testing" referred to is against engineering and safety standards (e.g., electrical safety), not medical interpretation.
4. Adjudication Method for the Test Set
Not applicable. As the testing relates to electrical safety and compliance with existing standards for medical devices, there would not be an "adjudication method" in the sense of resolving discrepancies in expert interpretation of clinical data.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, and effect size.
No, an MRMC comparative effectiveness study was not done. This type of study is relevant for diagnostic imaging or AI algorithms where human reader performance is being evaluated or augmented. The Daylite XeNon Light Source is an illumination device.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
Not applicable. This is a hardware medical device (a light source), not an algorithm or AI system. Therefore, standalone algorithm performance is not relevant.
7. The Type of Ground Truth Used
The "ground truth" for this device would be its adherence to established electrical safety standards and its functional specifications (e.g., power output, color temperature, continuous illumination adjustment) as compared to its own design specifications and general medical device requirements. These are engineering and performance specifications, not clinical outcomes or expert consensus on medical findings.
8. The Sample Size for the Training Set
Not applicable. This device is a hardware light source, not a machine learning model or AI system that requires a "training set."
9. How the Ground Truth for the Training Set was Established
Not applicable. As there is no training set for a machine learning model, there is no ground truth established for it in this context.
